Title: Roof for a building
Inventor: WACKER HEINZ
IPC: E04D1/24
Filed: 1988-06-30
Abstract: A roof is intended to be further developed such that the room temperature of an attic is reduced in the event of insolation or that the heat loss is reduced in the event of winter temperatures. The roofing tiles (10) of the roof according to the invention exhibit, on the underside, an insulating chamber (13) which is closed by a panel manufactured from a bitumen roofing sheet or by a sheet. The insulating chamber (13) is delimited laterally by peripheral border webs (12). An insulating core may also be introduced into the insulating chamber (13). In order to avoid a build-up of heat, two mutually parallel, spaced-apart border webs (12, 17) may be integrally formed on in the lower border region. This forms a ventilating chamber (18). The webs (12) and (17) are then equipped with mutually offset ventilating openings (18, 19). The roof is suitable for buildings of all types, but is particularly intended for roofs of residential buildings. <IMAGE>

Title: Method for using phase-gating controllers as frequency converters
Inventor: BOHN HEINZ DIPL PHYS
IPC: H02P27/02
Filed: 1988-09-06
Abstract: The invention relates to a method for using phase-gating controllers as frequency converters at discrete operating frequencies, especially for operating squirrel-cage motors for driving pumps, fans or the like at a reduced rotation speed, and its object is to achieve the advantages of the frequency converters, at least in the case of discrete working frequencies, without increased electrical outlay in the phase-gating controller. According to the invention, it is proposed for this purpose, in the case of a motor driven via a phase-gating controller, to obtain a voltage waveform which contains the desired operating frequency as the fundamental, by chopping the mains-side AC voltage at a stationary gating angle, by periodic alternation between half-cycles which are allowed through and which are inhibited (Fig. 3). <IMAGE>
